> The NativeFSLockFactory is causing the {{Lucene.Net.Replicator.IndexAndTaxonomyReplicationClientTest::TestConsistencyOnExceptions()}}
test to deadlock on .NET Framework 4.5.1.
> It is also seemingly causing random failures to:
>  * {{Lucene.Net.Store.TestMockDirectoryWrapper::TestDiskFull()}}
> I have confirmed over 15 test runs that reverting the changes from the following commits
eliminates the issue without producing any side effects:

> These include commits were introduced in [pull request #222|#222]([https://github.com/apache/lucenenet/pull/222])
and patches applied to it.
> It is unknown what the impact to consumers of 4.8.0-beta00006 is, but this issue appears
to be very rare judging by the tests.
